RE: 10gR2 RAC on single SLES9 node

No, I wasn't suggesting that you were implying Linux NFS is kosher for
outside of the playground - I was more commenting that the overall DBA
mentality of avoiding Linux NFS at all costs is not without historical
merit.

And of course, I know you work for Polyserve and certainly have the
chops to talk about Linux NFS (we know some of the same people).

Oh boy. Where in the world did I ever get misconstrued as suggesting
simple-stupid-plain-jane-vanilla-Linux servers exporting NFS mounts as
an option for "reasonably large RAC development environment" ?

The topic at hand is how to set up a multi-instance, single Server RAC
test/training kit where I say use NFS on loopback for simplicity.

Of course taking some braindead vanilla Linux FS and exporting it for
NFS mounting is NOT A SOLUTION for anything in the database arena.

There is a HUGE difference between NAS and NFS Server exports.
A NAS device (e.g., NetApp,EMC Cellera, HP EFS-CG) has a lot of
specialized NFS server-side stuff that makes it hold together for things
like databases or hard-hitting file serving. Since PolyServe is funding
the V4 NFS development at CITI, there is an ever-so-slight chance that
it will get even better.

Disclaimer. I work for PolyServe and I have intimate knowledge about
what databases on NAS are supposed to look like.
